I have a noise issue also but a little bit diffrent
Speed i think does not metter (it happens with 60/ 80/or 50)
but if I go for longer period with same speed car starts to have some kind of noise like whirlwind somewhere under the car
If i take my leg from acceleration pedal or I put it harder (so basicly i change speed ever for 1 mile/hour) it disepares
If i go with it for longer time suddenly i got some kind of noise hit (like something would hit a car) and it also disepares
Any one got issue like this??
I think that somehow somewhere air is going under a car a is starts to twist there... but i do not know how to find a place how it goes....
I checked all the shileds and there are ok...
